MODEM INSTALLATION
This chapter gives you advice and helpful hints on how to integrate the MTX-3G-Java Terminal into your
application from a hardware perspective.
1. Where to Install the Modem
There are several conditions which need to be taken into consideration when designing your application
as they might affect the modem and its function. They are:
1.1 Environmental conditions
The modem must be installed so that the environmental conditions stated in the Technical Data chapter
such as temperature, humidity and vibration are satisfied.
Additionally, the electrical specifications in the Technical Data section must not be exceeded.
1.2 Signal strength
The modem has to be placed in a way that ensures sufficient signal strength. To improve signal strength,
the antenna can be moved to another position. Signal strength may depend on how close the modem is
to a radio base station. You must ensure that where you intend to use the modem is within the network
coverage area. Degradation in signal strength can be the result of disturbance from another source; for
example, an electronic device in the immediate vicinity. More information about possible communication
disturbances can be found in section Operation 3.5 (Possible communications disturbances).
When an application is completed, you can verify the signal strength by issuing the AT command AT+CSQ.
Tip! Before installing the modem, use an ordinary mobile telephone to check a possible location for it.
In determining the location for the modem and antenna, you should consider signal strength as well as
cable length.
1.3 Connections of components to MTX-Java-IoT device
The user is responsible for the final integrated system. If not correctly designed or installed, external
components may cause radiation limits to be exceeded. For instance, improperly made connections or
improperly installed antennas can disturb the network and lead to malfunctions in the modem.
1.4 Network and subscription
Before your application is used, you must ensure that your chosen network provides the necessary
telecommunication services. Contact your service provider to obtain the necessary information.
• If you intend to use SMS in the application, ensure this is included in your (voice) subscription
• Consider the choice of supplementary services
